1. FIXED BAND OFF-AIR REPEATERS - OR2-SBLP1 SERIES Over the past decade, the growing diffusion of portable terminals has created the need for capillary coverage of the territory. Telecommunications networks must permit coverage services throughout the territory in the most extensive manner possible and, at the same time, guarantee the reliability and quality of the connection. From this point of view, the availability and quality of the services must be also guaranteed indoors, i.e. inside buildings.
2. OPERATING MODE Off-Air Repeaters for indoor applications are connected, by means of coaxial cables, to two antennas. The ‘donor antenna’, an outdoor one, interfaces the equipment with the Mobile Operator’s Base Transceiver Station (BTS). The ‘service antenna’, an indoor one, empowers the coverage of the indoor dead spot, and so it interfaces mobile terminals. The signal to be enhanced follows two distinct paths (FIGURE 1).

4. PROCEDURES FOR INSTALLATION AND POWER-UP • Before installing, carefully read the safety norms herewith attached. • The equipment must be connected to ancillaries specifically designed for the standard in use and the band to be enhanced. • The OR2-SBLP1 SERIES has been designed for indoor use only. Changes in temperature and humidity can influence the reliability of the equipment. The best place to install the equipment is a tempered and well-ventilated environment.
• Isolation between the antennas Since the equipment is a bi-directional amplifier, the isolation between the outdoor antenna (donor) and the indoor antenna (service) must be at least 15dB greater that the repeater gain. For example, if the repeater gain is 60dB, the minimum isolation between both antennas must be greater than 75dB. To guarantee the correct isolation between the antennas, it is necessary to plan for an adequate distance between them, both horizontally and vertically.
4.2. MECHANICAL AND ELECTRICAL INSTALLATION OF THE REPEATER Upon completion of the planning stage, you can proceed with the installation of the antennas (indoor and outdoor) and then with the installation and power-up of the repeater. Please remember: the OR2-SBLP1 SERIES is designed for indoor use ONLY. • Initial check Check the contents of the supply in terms on its completeness and/or eventual damage undergone by the material during transport.
• Connections A) Connect the cable from the outdoor antenna to connector N (f) BTS side, ref. 4 (ILL OR2-SBLP1 SERIES). B) Connect the cable from the indoor antenna to connector N (f) MS side, ref. 7 (ILL OR2-SBLP1 SERIES). C) Connect the power supply connector for the external AC/DC adapter (standard supply) to the power supply socket connector of the equipment, ref. 1 (ILL OR2-SBLP1 SERIES).
5. EXTRAORDINARY MAINTENANCE – TROUBLESHOOTING The diagrams below describe the steps to be taken in troubleshooting, i.e. the series of operations which, in case of equipment malfunction, permit the end-user to identify, and if possible, eliminate the causes of the fault.

PROCEDURE 1 PROBLEM GREEN LED (ref. 2, ILL OR2-SBLP1 SERIES) IS OFF START Does the equipment guarantee service just the same? no REFERENCE TO THE PROCEDURE 2 yes The LED is broken. The equipment can just the same extend the signal. END 91 080 0730F - OR2-SBLP1 SERIES FIXED BAND OFF-AIR REPEATERS Page 10 ENG Edit.
PROCEDURE 2 NO ’INDOOR’ SIGNAL PROBLEM The GREEN LED (ref. 2, ILL OR2-SBLP1 SERIES) IS OFF START Is the ext. AC/DC adapter connected to the equipment? (connector ref. 1, ILL OR2-SBLP1 SERIES) yes Is the ext. AC/DC adapter plugged into the line voltage? no Connect the ext. AC/DC adapter to the equipment no Connect the ext. AC/DC adapter to the line voltage yes LED = ON? END no no Correct the line voltage problem yes LED = ON? END no yes Does the ext.
PROCEDURE 3 NO INDOOR SIGNAL PROBLEM The GREEN LED (ref. 2, ILL OR2-SBLP1 SERIES) = ON START All connections ok between equipment and the antennas? no Make the connections Signal available? yes Outdoor signal available (> -70dBm)? yes END no yes REFERENCE TO PROCEDURE 4 no Contact the phone company (service provider) to solve the problem. END 91 080 0730F - OR2-SBLP1 SERIES FIXED BAND OFF-AIR REPEATERS Page 12 ENG Edit.
PROCEDURE 4 PROBLEM INDOOR SIGNAL is too WEAK START Outdoor signal level adequate (> -70dBm)? Proper outdoor antenna installed for signal available (ex. Directional antenna)? Antenna positioned and oriented correctly? no yes Install an antenna suited to the outdoor signal available, or change the position and orientation of the outdoor antenna. yes yes Signal available? END no Contact the phone company (service provider) to pinpoint the best signal source.
PROCEDURE 5 INDOOR SIGNAL IS PRESENT, BUT YOU CANNOT MAKE A PHONE CALL PROBLEM START Isolation between outdoor and indoor antennas = more than 15dB greater than repeater gain? no Adjust the horizontal and vertical distance between the antennas until proper indoor/outdoor isolation is achieved.
PROCEDURE 6 PROBLEM INDOOR SIGNAL IS NOT STABLE START Is the outdoor signal stable? no Try to stabilize the RF signal: Find a BTS that provides better reception, or change the position and orientation of the outdoor antenna. yes END Signal stable? no yes Contact the phone company (service provider) to solve the problem.
